LNHU080304-F57T WKP35S milling indexable insert — 0° negative rake, 0.4 mm nose radius, Walter Tools

The LNHU080304-F57T WKP35S is a rectangular milling insert engineered for productive machining of steel and cast iron, offering a balance of wear resistance and reliable chip formation in demanding industrial applications

• Tiger·tec Silver coating technology
• WKP35S coated carbide grade
• Negative rake 0° for robust cutting
• 0.4 mm corner radius for stable edges

Productive machining for steel and cast iron with consistent chip control

The coated WKP35S grade, part of the Tiger·tec Silver family, is optimised for the machining of steel and cast iron according to ISO material groups P and K. The combination of a wear-resistant coated carbide and an advanced chipbreaker supports controlled chip formation under the thermal and mechanical loads typical for these materials. This results in longer tool life and fewer interruptions in production, which improves overall process efficiency. The insert’s design reduces the risk of abrasive wear on the cutting edge and supports predictable tool-change intervals.

Geometry that enhances robustness and surface quality

The insert’s 0° negative rake geometry and 0.4 mm corner radius deliver a robust cutting edge that tolerates heavy engagement and interrupted cuts while maintaining dimensional stability. The rectangular shape (size 08) and the F57T chipbreaker are tuned to stabilise chips and reduce vibration during roughing and semi-finishing operations. As a result, the toolholder system benefits from reduced shock loads and the workpiece shows improved surface consistency, allowing reliable machining across series production runs.

Coating and substrate: longer life and repeatable results

A coated carbide substrate paired with the Tiger·tec Silver technology offers enhanced resistance to flank wear and crater wear, supporting repeatable performance over multiple workpieces. The coated grade is designed to perform under the higher temperatures experienced when machining steels and the abrasive conditions found in cast iron. The outcome is a favourable cost-per-part ratio: fewer insert changes and consistent part quality across shifts. For workshops seeking steady productivity, this insert provides a practical balance of durability and cutting performance.

FAQ

Is this insert suitable for machining both steel and cast iron?
Yes. The WKP35S grade and Tiger·tec Silver coating are designed for ISO groups P (steel) and K (cast iron), offering controlled chip formation and wear resistance for both materials.

What advantages does the 0° negative rake provide?
The 0° negative rake increases edge strength and stability under heavy cuts, making the insert more resistant to edge chipping during interrupted cutting and providing consistent dimensional results.

What is the effect of the 0.4 mm corner radius on machining?
A 0.4 mm nose radius improves edge robustness and contributes to a stable cutting action, which helps maintain surface quality during semi-finishing and roughing operations.

Which chipbreaker is fitted and what is its purpose?
The F57T chipbreaker is integrated to control chip shape and evacuation for P and K materials, reducing the likelihood of long, tangled chips and supporting reliable production runs.
